FAQ

Q: What is a ULID?
A: A ULID (Universally Unique Lexicographically Sortable Identifier) is a 128-bit identifier that encodes a millisecond-precision timestamp in the first 48 bits and 80 bits of randomness. Unlike UUIDs, ULIDs are sortable by creation time.
Q: What is the difference between ULID and UUID?
A: ULIDs are lexicographically sortable by time, making them better for database primary keys and log IDs. UUIDs (v4) are fully random with no time component. ULIDs use a Crockford Base32 encoding and are more readable than UUID's hex format.
Q: Is a ULID guaranteed to be unique?
A: Yes. ULIDs combine a millisecond timestamp with 80 bits of randomness. Even if multiple ULIDs are generated in the same millisecond, the random component makes collisions astronomically unlikely.
Q: Is any data sent to a server?
A: No. All ULID generation happens entirely in your browser. Nothing is sent to any server.
